[SOLVED] how can I check the url?

[shedokan]

Hello,

Is there a way to check if a user entered www. before the url?

thanks.

<?php
if (strpos($_POST['string'],'www')
{
echo "Yes they did";
}
else
{
echo "No they didn't";
}
?>

doesn't works and you forgot to end the if condition with a ) twice.

[trq]

<?php

  if (substr($_SERVER['SERVER_NAME'],0,3) == 'www') {
    echo 'www found';
  } else {
    echo 'www not found';
  }

?>

A revised version...

 

<?php
if(strpos($_POST['string'], "www.") !== FALSE)
{
echo "Yes they did";
}
else
{
echo "No they didn't";
}
?>

 

EDIT- oh you mean in the url that they used to enter the page lol. In that case thrope is right.

 

Orio.

<?php

  if (substr($_SERVER['SERVER_NAME'],0,3) == 'www') {
    echo 'www found';
  } else {
    echo 'www not found';
  }

?>

 

doesn't work I tried to echo $_SERVER['SERVER_NAME'] and one time I put the www and the other time I didn't and the result was the same both of the times and only echoed the url without www

[trq]

Thats wierd. I use that exact same variable to determin which configuratiosn to load for my framework. eg dev.domainname.com loads my developement version stage.domainname.com loads the staging configuration.

 

Never had a problem with it.

Check you dont have http:// before the www.

 

because without http:// substr($_SERVER[sERVER_NAME],0,3) will be "www"

 

with http:// substr($_SERVER[sERVER_NAME],0,3) will be "htt"

[trq]

No it wont. The http:// does not show up at in $_SERVER['SERVER_NAME']. It also much be in a valid request to the http server.

ow and I forgot to mention that I'm using a sub-domain

here's an online version of the script check you self and see that it doesn't work:

http://neostar.110mb.com/test-www.php

[trq]

So what exactly are you looking for? To see if your url starts with www, or contains www in the filename?

 

You really need to descibe what you want better. A subdomain normally won't work with www on the front.

[shedokan]

I want that if the user goes to neostar.110mb.com so it will redirect him to www.neostar.110mb.com.

[trq]

This would be best handled via mod_rewrite. I actually dought that www.neostar.110mb.com is a valid address for your site, simply because your entire site runs in a subdomain, but anyway. Try...

 

RewriteEngine on
RewriteCond %{HTTP_HOST} ^neostar.110mb.com [NC]
RewriteRule ^(.*)$ http://www.neostar.110mb.com/$1 [L,R=301]

 

in your .htaccess file.

owww... ok

I can't try your script yet because my webhost(110mb.com) doesn't support htaccess but they wll enable that feature so when they will I will test this script and post of phpfreaks forums any questions I will have.

thanks.
